Answer: a. cervical enlargement.
Explanation:
Cervical enlargement corresponds to the enlargement of the spinal cord. The spinal cord is the origin of the spinal nerves that contribute to an important task of supplying blood to the upper limbs.
The cervical enlargement results in an increase in the volume of the motor cells in the ventral part inside the grey matter. The motor neurons which are sited posteriorly supply to the upper limbs. Those which supply to the distal muscles are situated further posteriorly.

Answer:GCCGATTAGCGG
Explanation:
Chargaff base pairing rule state that the ratio of purines to pyrimidine in a specific DNA from any cell or specie must be equal in 1:1 ratio. In chargaff base pairing rule Cytosine C will pair with Guanine G on the complementary strand and Adenine A will pair with Thymine T on the complementary strand. C=G, A=T
So if the sequence 5' CGGCTAATCGCC 3' on the complementary strand will be
3' GCCGATTAGCGG 5'
